Rear Acura Spoilers;

Acura  (Japanese: Akyura) is the luxury vehicle division of Japanese automaker Honda Motor Company. It primarily competes with Buick, Lexus and Infiniti among others in the luxury vehicle segment. The brand has been used in the US, Canada, and Hong Kong since March 1986 to market Honda's performance vehicles and near-performance vehicles. The brand was introduced to Mexico in 2004 and to China in 2006. The Acura brand will be introduced in Russia at the end of 2008. Honda plans to introduce this to the Japanese domestic market (JDM) sometime around 2010. With the this brand, Honda is credited with being the first Japanese company to tap into the foreign luxury market. Before Acura, Japanese automobiles exports were primarily economical in design and largely targeted at low-cost consumers.

Rear Spoilers  generally function by disrupting or diffusing the airflow passing over and around a moving vehicle as it passes around the spoiler. This is accomplished by increasing the amount of turbulence flowing over the shape, "spoiling" the laminar flow and providing a cushion for the laminar boundary layer. Applications are varied, including using body panels, or most typically by adding an extruding attachment.

Occasionally spoilers are added solely for appearance with no thought towards practical purpose. The rear spoilers  is an automotive aerodynamic device whose intended design function is to 'spoil' unfavorable air movement across a body of a vehicle in motion. Spoilers are often fitted to race and high-performance sports cars, although they have become common on passenger vehicles, as well. Some spoilers are added to cars primarily for styling purposes and have either little aerodynamic benefit or even make the aerodynamics worse. Rear Spoilers for automobiles are often incorrectly confused with, or even used interchangeably with, wings. Automotive wings are devices whose intended design is to generate down-force as air passes around them, not simply disrupt existing airflow patterns. The main design goal of rear spoilers in passenger vehicles is to reduce drag and increase fuel efficiency  . While many often imitate wings and airfoils, these serve mostly decorative purposes. Passenger vehicles can be equipped with front and rear spoilers . Front spoilers  , found beneath the bumper, are mainly used to direct air flow away from the tires to the underbody where the drag coefficient is less. Rear spoilers, which modify the transition in shape between the roof and the rear and the trunk and the rear, act to minimize the turbulence at the rear of the vehicle. Sports cars are most commonly seen with front spoilers and rear spoilers . Even though these vehicles typically have a more rigid chassis and a stiffer suspension to aid in high speed maneuverability, a spoiler can still be beneficial. This is because many vehicles have a fairly steep downward angle going from the rear edge of the roof down to the trunk or rear of the car. At high speeds, air flowing across the roof tumbles over this edge, causing air flow separation. The flow of air becomes turbulent and a low-pressure zone is created, increasing drag and instability. Adding rear spoilers makes the air "see" a longer, gentler slope from the roof to the spoilers, which helps to delay flow separation. This decreases drag, increases fuel economy, and helps keep the rear window clean.

In 1986, following a decade of research, Honda opened 60 all-new dealerships in North America to support the automobile division. It was the first Japanese luxury brand to be introduced, and its initial offering consisted of two models: the Legend, a V6-powered sedan, and the Integra, available as a five-door and three-door hatchback. The success of these models led to competing Japanese luxury brand ventures (Toyota's Lexus and Nissan's Infiniti).
